After updating the firmware to 2.6.0, entering the PIN was very slow and stuck, having to turn it on and off to try again. Anyone else with this problem?
do I get it right that your PIN wasn’t recognized as valid by Trezor device?
If your device doesn’t accept the PIN, it means that you using an incorrect one. Every time you enter the wrong PIN, the time you have to wait for another try increases by a power of two. That is the reason why you need to wait so long for another attempt. After 16 incorrect attempts, your device wipes itself, making it possible to access your funds only with the use of your recovery seed.
The best solution to your issue is to factory reset your Trezor, recover your wallet with your recovery seed and set up a PIN again.
